Grithfang said:Contagion has the evil descriptor, so Heironeous (at lest in my campaign wouldn't grant the spell) and the cleric casting it would have to atone. It is not the same.
A LG cleric of a LG god cannot cast a cleric spell with an evil descriptor. It is not a matter of choice under the rules as written. The cleric cannot choose to cast it and suffer alignment consequences and then possibly atone later. Clerics have absolute alignment restrictions upon which spells they can cast, period.
For morally grey non evil descriptor spells there might be doctrinaire church codes against choosing to use them the same as there can be for arcane spells.
